Tux Paint installer; "tuxpaint-opencandy.iss", along with a file
with secret key info (not included in CVS, of course!), build
an OpenCandy-enabled version. The OC account is currently
maintained by Bill Kendrick <nbs@sonic.net>, lead developer.
For more info, see http://www.tuxpaint.org/docs/opencandy/
* Using $LDFLAGS when linking Magic tool plugins and Tux Paint binary.
Volkov Peter <volkov_peter@users.sourceforge.net> (SF.Net Bug #3389067)
* Collection of Mac OS X Updates:
-------------------------------
Produced by Eric Poncet <http://www.linguasoft.com/>
Commissioned by Harvey Ginter <harveyginter@gmail.com>
* Fix OS X 10.9 issue of current directory set by Finder
to something else than folder where app bundle resides.
* Customization support for Mac OS X (automatic, under XCode)
and Windows (manual).
* Some Mac OS X build / project changes & updates.
* Adjustments to Mac OS X fontconfig config file, to avoid warnings
and make things more robust.
* Updates to some #include's to catch up with newer library revisions.
* Tweaks to pixel read/write on Apple.
* Introduction of 'intprt_t' casting to avoid warnings on x64.
* Some additional debugging output.

* Accessibility Improvements:
---------------------------
* Added a mouse accessibility mode to avoid the need to drag the mouse.
("--mouse-accessibility")
by Ankit Choudary <ankit.goaldecided@gmail.com> (GSOC 2010)
with integration and fixes by
Pere Pujal i Carabantes <pere@fornol.no-ip.org>
* Added an option to display an on-screen keyboard when using the
'Text' and 'Label' tools. ("--onscreen-keyboard") [Experimental!]
by Ankit Choudary <ankit.goaldecided@gmail.com> (GSOC 2010) with
integration and fixes by Pere Pujal i Carabantes <perepujal@gmail.com>
and some code borrowed from xorg (keysymdef.h and en_US.UTF-8_COMPOSE
Authors?)
and xterm file keysym2ucs.c (function keysym2unicode
Markus G. Kuhn <mkuhn@acm.org>, University of Cambridge, April 2001
Special thanks to Richard Verhoeven <river@win.tue.nl>
Public domain.
* Keyboard can be used to move and click mouse ("--keyboard" option).
[Experimental!]
by Ankit Choudary <ankit.goaldecided@gmail.com> (GSOC 2010)
* See documentation in OPTIONS for how to use it.
* Joystick can be used to drive Tux Paint
by Ankit Choudary <ankit.goaldecided@gmail.com> (GSOC 2010)
with integration and fixes by Pere Pujal i Carabantes
* Use --joystick-dev to choose joystick (otherwise
uses the first joystick found on the system).
* Use '--joystick-dev list' to list available joysticks.
* Uses any of the buttons found in the joystick, no need for
configuration. (--joystick-buttons-ignore can be used to
ignore buttons.)
* The hat of the joystick moves one pixel at a time, useful to
carefully place the pointer.
* The ball of the joystick should also trigger pointer
motion.
* The responsivity of the joystick can be configured via command
line or config files:
* --joystick-slownes sets a delay at each axis motion event.
Allowed values from 0 to 500, defaults to 15.
* --joystick-threshold sets the minimum value of axis motion to
begin move the pointer.
Allowed values from 0 to 32766, defaults to 3200.
* --joystick_maxsteps sets the maximum number of pixels that
the pointer will move at a time.
Allowed values from 1 to 7, defaults to 7.
* Joystick buttons can be assigned used to activate certain commands
in Tux Paint (--joystick-btn-COMMAND options)
* Magic Tool Improvememnts:
-------------------------
* Magic tools can register themselves as paint with one click
(versus click/drag/release): MODE_ONECLICK. (e.g., "Ripples")
Utilized by mouse-accessibility feature.
* Magic tools can register themsevles as paint-with-a-preview:
MODE_PAINT_WITH_PREVIEW. (e.g., "Flower")
Utilized by mouse-accessibility feature.
* Other Improvements:
-------------------
* Random brushes avoid repeating the same frame twice.
* Showing a warning when using save-related options when "nosave" is set.
(SourceForge Bug #3327493)
* Quicker prompt window pop-up animation.
* Left/Right Stamp navigation buttons are purple, like the other (up/down)
scroll buttons found in Tux Paint.
(SourceForge Bug #2918289)
* Slightly improved mouse motion handling when Tux Paint is very busy
drawing or previewing. (e.g., when drawing a circle, you could often
end up with a "D" shape... now, you get more of a regular polygon shape
if Tux Paint is taking too long to draw. It skips some motion events,
rather than ignoring all motion events after the first 1/4th second.)
* Deleting files from Tux Paint's 'Open' dialog now moves them to
the user's Trash folder.
FIXME: Only on freedesktop.org systems (e.g., Linux)
(SourceForge.net Feature #3101084)
* Tux Paint (in windowed mode) now only centers itself if
no specific positioning has been provided via
the SDL_VIDEO_WINDOW_POS environment variable.
(SourceForge Bug #3138446)
* Creating thumbnails for the starters we provide.
(Speeds up 'New' dialog appearance.)
(SourceForge Bug #1417849)
Pere Pujal i Carabantes <pere@fornol.no-ip.org>
* On systems where Pango is used for UI text rendering, Tux Paint now
spawns a temporary thread during start-up (at the splash screen) to
allow "fontconfig" to generate its font cache in the background,
while showing the "please wait" animation, and responding to the US.
(Fontconfig takes a long time to generate its cache the first time
you run a Pango- and hence fontconfig-enabled application
(Tux Paint, Gimp, Inkscape, etc.), or after adding lots of new fonts
to your system).
SF.net Bug #2944951
* Thumbnailing (of UI elements, stamps, saved images, etc.) is now
gamma-corrected. See:
http://www.4p8.com/eric.brasseur/gamma.html
* Template images are now supported. Similar to Starters, they are
pre-drawn pictures to begin a new drawing with, accessed via the
"New" dialog. The "Eraser" tool will erase back to the original
picture (rather than a solid color).
Unlike Starters, they do not involve an immutable "layer" above the
drawing. They may be drawn over in their entirety.
* After switching into, or out of, a magic tool, the canvas is updated.
* Starter images can be in SVG (Scalable Vector Graphics) format.
(Avoids loading PNG if SVG with the same name exists.)
* Removed white artifacts from some Starters, and reduced file size
of some Starters.
* When scaling/smearing a picture or Starter, to fit the current canvas
size, it was not drawing on the far right or bottom edges, causing
Fill tool to 'spill'. (Example: fill one of the puzzle pieces on the
right or bottom of the 5x5 jigsaw Starter, and all pieces on the right
and bottom would get filled, too.)
* Starter images can be in KPX (Kid Pix Template) format.
(These appear to simply be JPEG with 60 byte's worth of Mac OS
resource fork header at the beginning.)
(Thanks to Sarah Curry for sharing some example templates to test.)
* When a default size was not specified, SVG-based Stamps would default
to the largest, which was canvas-sized. Now defaulting to a more
reasonable size. (And users can click the maximum size choice to get
the largest, canvas-sized rendition.)
(SF.net bug #2836471)
* Widened dialog windows, to help avoid word-wrap and overlap problems
with some prompts, in some locales.
(SF.net bug #2834461)
* Shape Tool now locks rotation into 15 or 5 degree steps, when the
radius of the shape is very small or small, respectively.
(SF.net bug #2837177)
* Shape Tool tries to avoid glitches where lines connect, when shape is
rotated. (Rotation of fixed-aspect shapes like Square and Octagon
stays within the angle of the corners. i.e., rotating a square 140 deg.
actually only rotates it 30 deg., since it looks identical,
sans glitches.)
(SF.net bug #2837177)
* Created a BASH tab-completion file for Tux Paint, so that
command-line options are easier to discover (without necessarily
needing to consult the man page, 'Options' documentation, or --usage
output).
* Text (and Label) tool doesn't flicker when typing or erasing text.
* Creation of thumbnails for personal starters and templates.
* Major rewrite of configuration and locale-setting code.
Albert Cahalan <albert@users.sourceforge.net>,
Bill Kendrick <bill@newbreedsoftware.com>
* Packaging all the metadata in the PNG file. Before a draw based
on a starter would have need 3 files: the draw, the starter and the
.dat file, whith the addition of the Labels tool this increased to
5 files. Now all this stuff is packed in customs chunks inside the
PNG file.
Pere Pujal i Carabantes <pere@fornol.no-ip.org>
* No longer directly accessing PNG structure members directly, now using
png_set_IHDR().
Thomas Klausner, SF.net Bug #3386433
* Adapted the interface to play nice too on touchscreen devices.
* Optimised PNG files using TruePNG and PNGZopfli, for smaller file sizes.

* Bug Fixes
---------
* Starter and template filenames with non-lowercase extensions (e.g. .JPG)
would fail to load.
SF.net Bug #191
* If a non-SVG starter or template with the same name as an SVG one
existed, it would be loaded instead of the SVG (despite a thumbnail
of the SVG appearing in the file selector).
SF.net Bug #191
* Image on right of dialogs would get scaled/cut-off even if there was
room for them.
* When using 'print delay' option, it would not allow printing the
first time until the delay had passed.
* Fixed error reporting when make_directory() fails.
(Fixes spurious
SF.net Bug #2765872)
John Popplewell <john@johnnypops.demon.co.uk>
* Buffersize for holding Starter and image filenames was way too low.
(Could crash with Starter images with very long filenames.)
* Shape tool would only resize a shape if you dragged down or right,
not up or left.
(SF.net Bug #2834320)
* tuxpaint-import tool uses BASHisms, so changed shebang to #!/bin/bash
(instead of #!/bin/sh).
* Added some missing examples to the default tuxpaint.conf file.
(Thanks to Aapo Rantalainen <aapo.rantalainen@gmail.com>)
* Default stamp size, in some situations, was very large
(due to some rules that allowed stamps to be, at maximum,
up to 2x width of the canvas, OR 2x height of the canvas, as long
as it wasn't larger than the canvas in the other dimension).
The stamp sizing buttons were unable to re-select that size.
The sizing button bug has been fixed, the rule has been adjusted to
allow a maximum overscan of 1.5x width-or-height, and if the maximum
size causes overscan, then a smaller size is used for the default
when the stamp is first used.
(SF.net Bug #1668235)
* Shapes tool now draws at mouse release to help painting with
touchscreen devices.
(SF.net Feature request #3008811)
* Shapes tool would left their preview on the canvas if you leave it
or change the shape before finishing to draw it.
(SF.net Bug #1057311)
* Example for 'savedir' in tuxpaint.conf suggested you needed /saved
at the end, which is not true. Added note explaining that actual
image files go under 'saved' subdirectory.
(Thanks to Marco Menardi)
* Saved images woose path contains non-ascii chars can now be opened on Windows.
Fixes http://sourceforge.net/p/tuxpaint/bugs/188/
* Ignoring ".pfb" (PostScript 'Printer Font Binary') fonts, to
avoid crashes.
Tux Paint 0.9.21 features nearly two dozen new Magic tools, as well
as updates to old favorites. Many of these were developed by six
students from around the globe during Google's 2008 Summer of Code
program, under the mentorship of Tux Paint developers.
Exciting new Magic tools include intelligent train tracks that
automatically connect when their paths cross, a realistic rainbow
tool, a fisheye lens effect, edge and silhouette tracing tools,
various string art effects, and a tool to fold the edges of your
drawing up from the corners. There is also a brush that paints with
'toothpaste', and others that paint with confetti, rain, snowballs,
and snowflakes! Additionally, many classic Magic tools (like Blur
and Tint) can now affect the entire drawing, instead of just a
selected area.
Coloring-book style Starter Images are now easier to make. Images
with transparency (alpha channel) are still supported, but
additionally, if no transparent layer is found, Tux Paint will
assume that white is the background color. This means you can now
draw or scan any simple black-and-white image and use it as a Tux
Paint Starter Image!
New in Tux Paint 0.9.21, the Text tool now supports bidirectional
languages like Hebrew and Arabic, thanks to the FriBidi library.
Tux Paint has also been translated to two new languages, Shuswap
and Songhay, and many other translations have been updated.
On Linux, environment variables (like "$HOME") may now be used when
setting directories for saving images or finding data files.
And of course, Tux Paint 0.9.21 incorporates a number of minor
improvements and bug fixes requested by the Tux Paint community.
For example, Tux Paint no longer drops out of fullscreen mode in
Windows if the [Windows] key is pressed (XP, 2000 and Vista only),
and it brings up an error window if it fails to print.
to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.
Suggested by tron in PR 47882
changes:
Scalable Vector Graphic (SVG) stamps, Japanese and Korean text entry,
improved printing and monitor support, and stamp categories are just
a few of the many improvements.
